Referring to the drawings 'in detail, the tool constituting the present invention comprises a sectional cylindrical body or housing A, its sections |0 and Il being disposed in end to end g55V matched relation to each other and within the section I is a dividing wall I2 separating said section into chambers or compartments I3 and I4, respectively, the former being accessible on removal of a top cover or cap I5, preferably removably threaded upon this section. 'Ihe chamber or compartment I3 constitutes a plastic r'eceiving and discharge well for putty or the like. The chamber or compartment I4 constitutes a gearing space for confinement of gearing hereinafter described. v

Built within the chamber or compartment I3 is a discharge mouth I6 in which is'removably socketed a delivery tube-like stem I1 which is provided with a locking pin or key I8 passable through a keyway I9 formed in the section I0 for the separable fastening of said stem in the body o r housing A and socketed in the mouth I6. The mouth I6 is tapered in the direction of the stem I1 and at the larger open portion thereof communicates with the chamber or compartment I3, the edge 20 about this larger open area of the mouth being radially disposed with respect to the center of said v'chamber or compartment I3 and constitutes a seat for a compressor wing or blade 2| having a sleeve-like hub 22 fixed to .a rotatable shaft 23 journaled centrally of the cornpartment or chamber I3 in the dividing wall I2 and cover orcap I5, respectively. The shaft 23 'Cil is carried through the chamber or compartment- I4 and also centrally through a dividing wall 24 in the section II and a cover piece 25 for the outer open end of the said section as Well as throughl a bearing plate 26 next to and spaced from the dividing wall 24 of the said section II. This bearing plate 26 is held xed upon posts or spacer members 21 joined with the dividing Wall I2 in the section I0. The dividing wall 24 and the cover piece 25 create within the section power spring 29, one end being suitably xed'to the section I I and the other end fixed to a sleevelike turning hub 30 loosely tting about the shaft 23 carried through the said space 28. 'I'his hub 30 through a train of speed reducing gears 3| has driving connection with the shaft 23 for rotation thereof when the power spring 29 is wound and active for driving purposes, the winding being accomplished by the turning of the section II. The train of gears 3| connected between the 'shaft 23 and the hub 30 is confined Within the chamber or compartment I4 in the section I0 and access had thereto by removal of the bearing plate 26 on separation of the sections I9 and II. The cover plate 25 is made fast to the shaft 23 by a nut 32 separably threaded on the said shaft. -The rotation of the shaft 23 turns the wing or blade 2| within the chamber or compartment I3 for forcing the plastic material 33 packed therein through the mouth I6 for discharge through the stem I1 in a manner presently described.

In lling the chamber or compartment I3, the wing or blade 2| is in a position remotely from the edge 20 about the larger opening area of the mouth I6 which constitutes a seat for the Wing or blade 2| .when the material 33 has been completely spent or discharged from within the chamber or compartment I3 in the use of the tool.

Fixed to the dividing wall 24 in the section about the hub 3U loose upon the shaft 23 is a ratchet wheel 34 with which engages an escapement dog or pawl 35, being pivoted at 36 and spring tensioned at 31, while acting upon this pawl'or dog 35 is a tripping lug 38 extended through a clearance slot 39 and projected from al I I a space 28 `for a winding and unwinding coiled finger operated actuating trigger 40, pivoted at 4I and extended through a way 42 to without the section I0 of the body or housing A for manual control thereof. The pawl or dog 35 functions for locking the spring 29 in a wound condition, the winding of the said spring being had by the turning of the section II and this pawl or dog 35, when actuated by the trigger 4I), allows a step by step escapement action upon the spring 29 for the gradual or step by step unwinding thereof and in this manner the wing or blade 2| will be relieved of pressure so that it can be turned away from the mouth I6 to a remote place therefrom Within the chamber or compartment I3 to allow for the lling thereof with the plastic material 33 and a maximum loading of such material within this chamber or compartment. Furthermore, this escapement varies the tensioning action of the spring 29 for the driving of the train of gears 3| and the compression activity of, the wing or blade 2| upon the load or charge within the compartment or chamber I3 in the section I0 of the tool. 'Ihe compression activity of the wing or blade 2| on the material 33 regulates the speed of discharge of such material from the tool and the control of this discharge being hereinafter set forth.

The section I exteriorly thereof is formed with a serrated, corrugated or uted annular bead or gripping area 43 which enables the convenient turning of the section II for the winding of the spring 29 within the space 28. The hub 30 is latched by the pawl or dog 35 against turning movement when the spring 29 is being wound.

The keyway I9 in the section I9 provides a vent for the escape of air rearwardly of the compressor wing or blade 2| to assure against a possible vacuum within the chamber or space I3 in the operation of the device.

The discharge stem I1 is provided with a valve casing 44 for a cutoff turn plug valve 45 operated by a hand lever`46. This valve 45 is maintained in a cutoi position by a coiled spring 41 connected to its turning arbor and to the valve casing 44 exteriorly thereof. The casing 44 and the hub 48 of the lever 46 are provided with stop shoulders 49 and 59, respectively, so that the valve 45 will be held through these stop shoulders in a cuto position, this being the normal position of said valve. The valve 45 controls the discharge of the plastic substance or material from within the compartment or chamber I3 in the section I0 of the casing or housing A when the device is operated.

Removably fitted on the outer end of the stem I1 outwardly of the valve 45 is a discharge nozzle 5|, the major portion of which is of substantially triangular shape in cross section and constitutes the tip 52 of said nozzle. Slidably tted exteriorly against one flat side of the tip 52 is an adjustable flexible putty knife blade 53, being held slidably fitted with the said tip by guide lugs 54 and is provided with a finger grip 55 for manual control thereof. The tip 52 of the nozzle 5I delivers the plastic substance or material from the device in substantially triangular ribbon or strip form and the putty knife blade 53 presses this strip form into place for the sealing of panes or panels within window sashes, doors or the like. When the tip 52 is brought into a restricted or contracted place where there is required the application of the plastic substance or material, the blade 53 is retracted sumciently to allow the proper application of the plastic substance or material at such point or location and in this 5 in a clip 51 about the hub 3o and in this fashion the end of the spring 29 is made secure thereto.

In Figure 14 of the drawings there is shown a slight modification of nozzle, which is indicated generally at 58, and isformed with a flattened discharge tip 59 which delivers the plastic substance or material through this nozzle 58 in a fiat, ribbon-like form. In this instance of use of thenozzle 58, the putty knife blade- 53 is dispensed with, being required that a separate putty knife be used for the application of the flat, ribbon-like substance to the work.

The mouth I6 within the chamber or compartment I3 forms a dividing partition between the Wall of. the section I and the hub 22 of the wing hand carrying of such device, this being illustrated in Figure 1 of the drawings.

By the turning of the valve 45, the quantity of plastic substance or material to be discharged from the chamber or compartment I3 under compression can be readily controlled and the device in its structural make-up is susceptible of convenient handling and will eliminate waste of the material or substance as well as enabling a 40 smooth, neat and clean application thereof to the work.
